Little FOCer REV3.1 ESC Electric Speed Controller - BYOH:
Little FOCer Rev3.1 ESC Electric Speed Controller BYOH (Bring your own Heat-sink version)
- The Little FOCer without a heat sink
- Uses Vesc based firmware
- DC Input 12 Gauge wire to XT60 Male
- Phase Output 12 Gauge wire to 4mm Female Bullet connectors
- On board IMU for balance applications
- Integrated Bluetooth NRF 52840
- DRV less design
- Sophisticated fault detection for over-current, over-voltage, gate drive errors, and more
- Easy On/Off capability with latching switch of choice
- ESD Protected IO
- 72mm x 84mm PCB footprint
- ADC1 and ADC2 internally equipped with 10k Ohm pulldown resistors.
The capacitors and JST connectors' are mounted on the opposite sides of the mosfets so that the motor controller can be mounted to a metal plate or other custom heat sink solution. This is typically the best option for fitting inside the controller box of a balance board.
New features in Rev3:
- Increase current limits
- support for phase filters
- ASS support (Advanced Sensorless Startup)
